Which part of the microscope is used to make small adjustments in the image of an object?
A)Eyepiece
B)Fine Adjustment
C)Coarse Adjustment
D)Objective lens
Answer:
The part of the microscope that is used to make small adjustments in the image of an object is the fine adjustment.
Explanation:
In the optical microscope, the fine adjustment knob allows precise focusing of the sample being studied. This means making minimal adjustments in order to better observe the microscopic image.
After the initial focusing with the coarse adjustment knob, with the fine adjustment it is possible to highlight the details that require more attention, as well as the refringency of the sample, if it exists.
The other options are not correct because:
A. Eyepiece is the lens that receives the image from the objective lens, that has contact with the eyes of the observer.
C. Coarse Adjustment is the rough magnification, used for the initial approximation of the image.
D. Objective lens enlarges and defines the image of the sample on the slide.

What impacts would suburban development have on undeveloped deciduous forest and meadow ecosystems?
Answer:
Impacts of suburban development on undeveloped deciduous forest and meadow ecosystems are - : loss of biodiversity , excessive land use , deforestation , degradation of air quality , increase in the amount of greenhouse gases , therefore leading to environmental loss .
Explanation:
SUBURBANIZATION -: Suburbanization is a demographic change, resulting in the creation of (sub)urban sprawl, from core urban areas to suburbs. Low-density, peripheral urban areas are increasing as a consequence of the migration of households and companies out of the city centers. (Urbanization, which signifies a demographic change from rural areas to urban centres, is inversely related to suburbanization.)
Within the central urban area, many residents of metropolitan regions work and prefer to live in satellite communities called suburbs and commute to work by car or mass transit. Others have taken advantage of advances in technology to operate from their homes.
Environmental Implications -: This can have negative effects on the community with the growth of suburbanization and the spread of individuals living outside the city. Suburbanization has been related to an increase in the mileage of automobiles, an increase in land usage, and an increase in the use of residential electricity. These suburbanization factors then induced air quality deterioration, increased use of natural resources such as water and oil, and increased quantities of greenhouse gases. This causes increased use of oil and gas as well as an increase in pollution as the use of cars to drive to and from the workplace grows. This will then cause air pollution and degrade the air quality of a region with a rise in emissions from vehicles. Suburbanization is increasing, leading to an increase in housing growth, which causes the consumption of land and land available to increase.

If a radiometric age can be determined is there any use for a relative age? Why or why not?
Answer:
Radiometric dating calculates an age in years for geologic materials by measuring the presence of a short-life radioactive element, e.g., carbon-14, or a long-life radioactive element plus its decay product, e.g., potassium-14/argon-40. The term applies to all methods of age determination based on nuclear decay of naturally occurring radioactive isotopes. Bates and Jackson (1984)

(Hint : which patient is more antigen before or after the transfusion ? ) male and one female who each one needs one pint of would you give to have an exposure to Rh O blood more likely to have an
Answer:
Explanation below
Explanation:
There are different form or type of blood group. These include blood group A, B, AB and O.
The blood group AB is usually known as the universal recipient while the blood group O is the universal donor.
A universal donor can donate blood to all other blood groups, while the Universal recipient can receive blood from all other blood groups.
In this case, two patients, one with blood group A and the other with blood group AB, with only one available group A type pint for transfusion. The best thing to do in this case is to give the blood to group A patient and get any other blood group pint of blood for the group AB patient. This is because the blood group AB patient can receive blood from any of the blood groups.
